Key takeaways
  • Because a Henson trust deliberately gives the beneficiary no fixed entitlement, the trustee's judgment is doing a lot of the work the trust document itself cannot.
  • Managing investments, records, and distributions over years requires consistency, not just good intentions.

Setting up a Henson trust is only half the job. The other half — often the harder half — is deciding who will actually run it, for however many years or decades the trust needs to exist. Because a Henson trust gives the trustee complete discretion over payments to the beneficiary, the person you choose is going to make real, ongoing decisions about someone you love, likely long after you are no longer there to guide them.

This article walks through what to weigh when choosing a Henson trust trustee, and when a professional or corporate option might make more sense than a family member.

Why This Decision Carries More Weight Than a Typical Trustee Choice

Because a Henson trust deliberately gives the beneficiary no fixed entitlement, the trustee's judgment is doing a lot of the work the trust document itself cannot. A trustee who is disengaged, uncomfortable with the responsibility, or in conflict with other family members can leave the beneficiary worse off than a differently drafted trust with a stronger trustee ever would.

Qualities to Look For

Individual (Family) Trustee vs. a Corporate Trustee

Individual Family MemberCorporate Trustee (Trust Company)
Personal knowledge of the beneficiaryUsually deep and personalGenerally limited unless deliberately cultivated
Continuity over decadesDepends on that person's own life circumstancesInstitutional — doesn't personally age, become incapable, or move away
Investment and tax expertiseVaries widelyGenerally built-in professional expertise
CostOften unpaid or modestly compensated if familyOngoing professional fees for administration
Family conflict riskCan be higher, since the trustee may also be a beneficiary's sibling or relativeGenerally lower — a corporate trustee has no personal stake in family dynamics
Best suited toFamilies with a capable, willing, and available member; shorter or simpler trustsLarger trusts, complex assets, family conflict, or when no suitable individual is available

Can You Name More Than One Trustee?

Yes — many families name co-trustees, such as a family member paired with a professional advisor or corporate trustee. This can combine personal knowledge of the beneficiary with administrative and investment expertise, though co-trustees generally need to agree on decisions, which can slow things down if their views differ significantly. The trust document should address how disagreements between co-trustees are resolved.

Should the Trustee Be a Beneficiary's Sibling?

Naming a sibling is common and often works well, but it comes with a specific risk to think through: a sibling trustee may also be a contingent beneficiary entitled to whatever remains in the trust after the primary beneficiary's needs are met. That overlap can create a subtle conflict of interest — every dollar the trustee-sibling declines to spend on the primary beneficiary is a dollar that may eventually come to them instead. This does not mean a sibling can never serve, but it is worth discussing openly, and some families choose a co-trustee or professional to help manage that dynamic.

Frequently asked questions

Does a Henson trust trustee need to understand disability benefit rules?

A good trustee should have at least a working understanding of how the beneficiary's government benefits interact with trust distributions, or be willing to get advice on that point before making significant payments, since the wrong kind of distribution can put those benefits at risk.

Can I change the trustee of a Henson trust after it's created?

Whether and how a trustee can be changed depends on the trust document and general trust law — see our companion article on removing a trustee for the general process where informal replacement isn't possible.

Is it better to name one trustee or several?

There is no universally right answer — a single trustee can act quickly and decisively, while co-trustees add oversight and combined expertise at the cost of some speed. The right choice depends on your family and the assets involved.

Can a lawyer or accountant serve as trustee instead of a family member?

Yes, a professional can be named trustee, either alone or alongside a family member, and this is a common solution where no family member is well suited to the role or where added objectivity is valuable.
